The difference comes in the
>Man shares his woman
part. In a harem (or reverse harem) there's no "X's Man/Woman", it's basically a mix of a free-for-all and a first come first serve relationship with a central figure. If there's a situation where a wife is telling her husband to go fuck other girls, that's just Netorase.
Now if the central figure takes one of their harem pieces and tells them to go fuck someone from outside the harem, then you're talking about something different.
